Question

What is Positional isomerism?

Answer 1

Positional isomerism:

• Positional isomers are constitutional isomers with the same carbon skeleton and will have the same functional group.
• They differ from each other in the position of the functional groups on the carbon chain and the phenomenon is known as positional isomerism.

Example: 1-Chloropropane and 2-Chloropropane

• 1-Chloropropane contains the chlorine atom at the first carbon and 2-Chloropropane has chlorine atom at the second carbon.
